change the caliper too , I got my bike ready made motard from a member here. Forks are softs for serious racing use the harder setting front and back, I havent try yet a dirt section but i guess it will work good with the stock sock/fork. Buy a full pipe, jet kit and filter and if you have any leftover money get a set of cams (they make a nice difference!) Not sure what gearing your bike has but mine was 15/44 and i went 15/41 and goes much better.
